Hi, This email is to discuss whether we can abandon 0009-Pike-Rebase-Enhanced-force-deletion.patch in StarlingX/Cinder. This patch resolves the problem that a volume is attached to a non-existed VM and can't be deleted. I talked with Openstack/Cinder community. As Cinder uses new attach/detach workflow, now this problem doesn't exist. Users can use "cinder attachment-list" to list all the attachments, and then delete them. After that, the volume can be deleted. Fang Liang also did such test, it works. So I think we can abandon this patch. Any objections? Best wishes Lisa
